Marc Guggenheim vertelde dat het kostuum een bewuste keuze is geweest: “I don’t think Diggle looks at it as a costume per se. Oliver [Stephen Amell], in the last season, gave him advice in terms of concealing his identity, and so Diggle approaches it from a very practical standpoint. He followed Oliver’s advice and he’s got a means of concealing his identity, but I think Diggle would probably react to anyone calling it a costume.”
